If the target is an integer or fixed point format, round-to-nearest-even is used, unless the conversion is explicitly documented as using another rounding behavior, such as round-to-nearest for FLOAT to SNORM, FLOAT to UNORM or FLOAT to SRGB. Round-to-zero is used during conversion to another float format. ![]() Conververting from a higher range representation to a lower range representation Whenever a floating point conversion between different representations occurs, including to or from non-floating point representations, the following rules apply. For complete detail, refer to the SRGB color standard, IEC 6, at IEC (International Electrotechnical Commission). Roughly, if this nonlinear progression, SRGB, is displayed as a sequence of colors, it would appear as a linear ramp of luminosity levels to an "average" observer, under "average" viewing conditions, on an "average" display. However unlike UNORM, with SRGB the sequence of unsigned integer encodings between all 0's to all 1's represent a nonlinear progression in the floating point interpretation of the numbers, between 0.0f to 1.0f. Similar to UNORM, in that for an n-bit number, all 0's means 0.0f and all 1's means 1.0f. a 3-bit UINT represents the integral values 0, 1, 2, 3, 4, 5, 6, 7.Ī floating-point value in any of the representations defined by Direct3D. an 3-bit SINT represents the integral values -4, -3, -2, -1, 0, 1, 2, 3. A sequence of evenly spaced floating point values from 0.0f to 1.0f are represented. Unsigned normalized integer, meaning that for an n-bit number, all 0's means 0.0f, and all 1's means 1.0f. This results in a set of integer representations for evenly spaced floating point values in the range (-1.0f.0.0f), and also a complementary set of representations for numbers in the range (0.0f.1.0f) There is a single representation for 0.0f, and a single representation for 1.0f. There are thus two integer representations for -1.0f. In addition, the second-minimum number maps to -1.0f (e.g. the 5-bit value 01111 maps to 1.0f), and the minimum value means -1.0f (e.g. Signed normalized integer, meaning that for an n-bit 2's complement number, the maximum value means 1.0f (e.g. The following set of terms are subsequently used to characterize various format conversions. Converting from a lower range representation to a higher range representation.Conververting from a higher range representation to a lower range representation.where to modify the code and so on.The following sections describe how Direct3D handles conversions between data types. Feel free to ask more questions about how to accomplish your desired change, e.g.You should take this statement as an encouragement to get involved in developing the program.If I happen to reply Patches are welcome, this means that I don't have time to work on it, but if you happen to fix it, I will consider including your patch in the official program.They might even refine it to the point it will be accepted into the official program. Even if I don't accept your changes, they will be easier to discover by other people who might want that particular change.A good way to do this is to create a Pull Request on GitHub. You are expected to contribute your changes.This is why everything is open source, it allows you to make any customization you need on your own.I build my things in my free time and I don't get paid to do any of this, so don't be rude if I don't change my program to behave exactly how you want.If applicable, prefix your post title with the program it concerns, e.g.I will remove posts that contain anything offensive, hateful or discriminatory, and most likely ban the offender.
